Term Rewriting System R:

   [x, y, z]
   *(x, *(y, z)) -> *(*(x, y), z)
   *(x, x) -> x

Termination of R to be shown.


Removing the following rules from R which fullfill a polynomial ordering: 

   *(x, *(y, z)) -> *(*(x, y), z)
   *(x, x) -> x

where the Polynomial interpretation:
POL(*(x_1, x_2)) = 1 + x_1 + 2*x_2
was used. 



All Rules of R can be deleted.
